'IMPROVEMENT'IN HUBS FOR VEHICLE-WHEELS.

Specification forming part of Letters Patent No. 162,81 3, dated May 4,1875; application filed September 8, 1874.

To all whom it may concern Be it known that I, WILLIAM GALLAN, of thecity. of Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Process to Prevent Hubsfrom Splitting; and I do hereby declare that the following is a full,clear and exact description thereof, which will enable others skilled inthe art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

Figure l is a plan view of a hub, showing myimprovement. Fig.2 is adetached view of one of the tacks.

The object of this invention is to prevent a hub from splitting, eitherbefore or after the spokes have been driven, or while they are beingdriven, and, at the same time, not to impair the beauty and symmetry ofthe hub. This device is rendered important from the fact that if a hubsplits while the spokes are being driven, or after they have beendriven, and the wheel has been finished and painted, the wheel isspoiled, and, as a general rule, a new one has to be substituted 5 or,if not, its beauty is marred by iron bands which have to be driven onthe hub to protect it from splitting further. This invention consists insewing the fibers of the wood together and covering up the stitches by acelluloid band, as will be hereinafter more fully set forth.

Two grooves, a, three-fourths of an inch wide, by one-eighth of an inchdeep, more or less, according to the size of the hub a, is

made therein, one in front of the spokes and the other behind them, asshown; and in said grooves are driven two or more rows of double prongedstapleshaped tacks, 1), (Miles patent carpet-tacks serve the purposeadmirably,) each row breaking joints, as it were, or overlapping theother alternately, thus actually sewing the fibers together andrendering it almost impossible to split the hub. This being done, thegrooves are filled up with bands made from celluloid, patented by J. W.and I. S. Hyatt. These bands, being elastic, will not break, and, if thewood shrinks, will shrink or contract with it.

Hubs have heretofore been prevented from splitting by annular bands,which have been placed around them, and this I disclaim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. The combination of the hub a, with the bent double-ended tacks b, thetacks being driven into the hub and made to overlap each other,substantially as and for the purposes described.

2. The combination of the hub a, having one or more annular grooves inits surface, the bent double-ended tacks b, and fillingbands at,substantially as set forth.

In testimony that I claim the foregoing as my own invention, I affixhereto my signature in presence of two witnesses.

WILLIAM GALLAN.
